Hello, I'm trying to write a custom agenda command that cycles through a list of names and builds an agenda block for each one with his tasks. I wrote a command, that I have called org-sec-tasksbymember that throws a list of tags-todo with the parameters I want. For example, for a list of members ("Me" "Pablo" "Miguel" "Carlos"), defined in a variable, the evaluation of (org-sec-tasksbymember) throws: ((tags-todo "+Resp=\"Me\"") (tags-todo "+Resp=\"Pablo\"") (tags-todo "+Resp=\"Miguel\"") (tags-todo "+Resp=\"Carlos\"")) If I define a custom agenda command like (without using the command): ("q" "Tasks by member" ((tags-todo "+Resp=\"Me\"") (tags-todo "+Resp=\"Pablo\"") (tags-todo "+Resp=\"Miguel\"") (tags-todo "+Resp=\"Carlos\""))) It works, but if use this agenda command: ("q" "Tasks by member" (org-sec-tasksbymember)) I got an error of Wrong type argument: listp, org-sec-tasksbymember I can't find a solution. Can anyone help me. I'm sorry if this is dumb.
